To all whom it may concern:

Be it known that I, RAYMonn .O.'lVoNEs, a citizen of the United States, residing at li/Iaplewood, county of Shelby, and State of Ohio, have invented certain new and useful Improvements in Manifold liocks, of which the following is a specification.

This invention relates generally to devices adapted to be applied't'o automobiles or motor vehicles generally to prevent operation of the engine during the absence of the driver or owner, the invention having more particular reference to a device adapted to be applied to the engine manifold to close and lock the passage therethrough.

The invention has for an object to provide an inexpensive and easily applied and operated device of this kind, and one which may be applied. readily to engines of all ordinary types o For further, comprehension of the invention reference will be-had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the'drawings is a face view of the device with one plate removed.

Fig. 2 is a section on the line 22 of Fig.

1, showing the device in position.

Fig; 3 is a section on the line 3-3 of Fig. 1. Fig.4. is aside view of the device in position on an intake manifold. a

Fig. 5 is a view of a split bolt for securing the device to the manifold. K

In the drawings the intake manifold of an internal combustion engirelsuch as is used on automobiles and motor vehicles generally is shown at-l and the carbureter at 2. The manifold has the usual flange 3 on its outer end and the outlet passage l of the carbureter the usual flange 5 whereby these parts are ordinarily connected together.

According-to my invention I interpose between these fianges a flat and relatively thin casing containing a movable member which may be moved into and out of position closinggthe intake passage to the engine.

i ls here shown. this casing comprises a pair of plates 10 and 11 roughly rcctan'gu lar shape between which is interposed a recessed spacer member 12 1n the recess of which the said movable member is located,

U y i a r v l -Specification of Letters ratent. ,Patented July. 1, 1919.

' Application filed; March a5, 1919. SerialNoQ285ld13: if i the plates-l0 and l l and spacer 12 being suitably united asby the rivets 1301- by suitable screws which are secured in place after insertion of the said member.v

The casing, thus provided is formed near one corner thereof with an aperture 15 001'- responding in size to thegmanifold passage,

and is also provided on, opposite sides of this aperture with bolt holes 16 which reg-- is'ter with the usual bolt holes in the flanges between the plates/10 and 11. leads first downwardly "from the aperture 15 as atQQ and. then horizontally toward the opposite side-0f thecasing as at 21, and then'up wardlyas at '22 .to the outside of the casing.

The locking member is of a thickness to fit easily in this recess and is of approxi- -mately. siinilai' sliape thereto, comprising a vertical port-ion 27 which is disposed in the recess portion 22 and projects at its outer end through the casing. This projecting end maybe provided with a lip or head as indicated at 28 whereby it may conveniently be grasped by the hand.

.As shown in the drawingsthe horizontal portion 21 of the recess in the casingisof considerably greater vertical dimensions than the horizontal portion 26 ,of the member therein thus permitting vertical movementof the latter whereby the short vertical portion 25 thereof may be moved from the position shown in full lines in Fig. 1 in which the passage to; themanifold is unobstructed to that shown in broken lines, in

which the passage is closed;

Formed in'the vertical portion 27 of the manifold closing member is an openingBO which is adapted to register with openings 31 and 32 in the plates-1O and 11, when the manifold is closed, with the closing member in'theposition shown in broken lines. The

bow 33 of a padlock 34; may be passed through these openings and the padlock closed thus locking the parts in' position. closing the passage through the manifold.

To open the manifold it is only necessary to unlock and remove the padlock 34 and push. the-head 2S inward; lVhen the lock is to be applied the head is pulled outward until it stops when the openings 30,31 and 32 will be in registry and the padlock may be applied.

To prevent easy withdrawal of the bolts 35 which clamp the casing between the flanges 3 and 5 these bolts may be split and have their ends forced outwardly as at 36 to render more difiicult the unscrewing of the nuts 37.

As will be apparent this manifold lock may be inserted in a manifold with a minimuin of trouble and without the necessity of other work than removing the usual bolts which clamp the carbureter to the manifold. Having thus described my invention and set forth the manner of its construction, what I claim as new and desire to secure by Letters Patent is I 1. A manifold lock comprising a thin casing having an opening therein adapted to register with the passage through the manifold, a substantially U-shaped member slidably mounted in said casing to move into and out of position closing the manifold passage, said member having a projecting handle portion rigid therewith. and means for locking said member in position closing the manifold passage. 1

2. A manifold lock comprising athin casing having an opening therein adapted to register with the passage-through the manifold, a member slidably mounted in said casing consisting of parallel portions one of which is adapted to project across the said opening and the other projecting exteriorly to the casing in the form of a handle, a rigid cross piece uniting the ends of said parallel portions, and means whereby said second mentioned parallel portions may be locked to the casing.

ister to receive a locking device when the first mentioned parallcl portion is closing the said opening into the manifold.

4. A manifold lock comprising a thin casing having an opening therein adapted to register with the passage through the manirespective parts of the said member, said cross portion being widened to accommodate movement of the member into and out of closing position, said casing and said handle portion being formed with openings adapted to register to receive a lock when the member is .in closing position.

5. A manifold lock. having an opening therein in register with the passage through the manifold, a substantially U-shaped member longitudinally slidable to cover or uncover said opening, and means for locking said member in position.

6.'A manifold lock comprising a casing having an opening therein in register with the passage through the manifold. a substantially U-shaped member slidable therein. a shutter on one end of said member and a handle on the other end thereof. said handle being adapted to be reciprocally moved to cause said shutter to cover or uncover said opening, and means to lock the same in position.

7. A manifold lock having a frame and opening therein to register with the passage through the manifold, a' substantially U- shaped member slidable therein, a shutter on one end of said member and a handle on the other end thereof, eyes in said member and in said frame, and locking means for said member adapted to pass through the said eyes.

In testimony whereof I have affixed my signature.
